Environmental testing - Part 2-1: Tests - Test A: Cold

Edition date: 2025-09-23
In Force
Available languages: French, English
Summary: IEC 60068-2-1:2025 specifies temperature tests at low temperatures, generally referred to as "cold tests", that are applicable to non-heat-dissipating and heat-dissipating specimens, to determine the ability of components, equipment, or other articles to be used, transported or stored at low temperature.
This document is applicable to energized as well as non-energized specimens that normally achieve temperature stability during the test. The specimens can be subject to test in packed condition (to simulate transportation and storage) or in unpacked condition (to simulate use).
This document does not specify tests to determine the impact of temperature changes on specimens.
This seventh edition cancels and replaces the sixth edition published in 2007. This edition constitutes a technical revision.
This edition includes the following significant technical changes with respect to the previous edition:
a) revision of the introduction and scope;
b) inclusion of new figures and symbols for clarification purposes;
c) clarification of the test procedure for ascertaining high or low air velocity in the test chamber;
d) clarification of the requirements for measuring points around, on or in specimens;
e) reintroduction of the nomogram procedure for the correction of the conditioning temperature when testing with high air velocity (Test Ad and Test Ae);
f) revision of the temperature tolerances of the test;
g) revision of standardized requirements for the relevant specification and test report;
h) inclusion of the advantages and disadvantages of the testing procedures.

L'IEC 60068-2-1:2025 spécifie les essais de température à basse température, généralement appelés "essais de froid", qui sont applicables aux spécimens non dissipateurs de chaleur et dissipateurs de chaleur, afin de déterminer l'aptitude des composants, équipements ou autres articles destinés à être utilisés, transportés ou stockés à basse température.
Cette septième édition annule et remplace la sixième édition parue en 2007. Cette édition constitue une révision technique.
Cette édition inclut les modifications techniques majeures suivantes par rapport à l'édition précédente:
a) révision de l'introduction et du domaine d'application;
b) ajout de nouvelles figures et de nouveaux symboles à des fins de clarification;
c) clarification de la procédure d'essai pour la vérification de la haute ou faible vitesse de l'air dans la chambre d'essai;
d) clarification des exigences pour le mesurage des points autour ou au-dessus des spécimens;
e) réintroduction de la procédure d'abaque pour la correction de la température d'épreuve lors de l'essai avec haute vitesse de l'air (Essai Ad et Essai Ae);
f) révision des tolérances de température de l'essai;
g) révision des exigences normalisées pour la spécification applicable et le rapport d'essai;
h) ajout des avantages et inconvénients des procédures d'essai.
